data software.
Table 1–1: Detector capabilities
Capability Description
Stand-alone programmability Stores as many as five user-defined
programs (or methods) consisting of as
many as 50 programmable, timed events
and two threshold events each.
Single or dual-wavelength Monitors absorbance at one or two
discrete wavelengths.
Wavelength verification reference filter Ensures wavelength accuracy.
Automatic, second-order filter Automatically engaged for wavelengths
of 370 nm and greater and removed for
wavelengths of 369 nm or less.
Spectrum scan and storage Supports spectrum scan, display,
subtraction, storage, and playback, in
addition to standard absorbance and
UV/Vis functionality.
Method editing and storage Supports basic method programming,
storage, and retrieval from the front
panel.
Full diagnostic capability Supports built-in diagnostic tools to
optimize functionality and performance.
Two contact closure outputs The detector has two configurable
switches, each of which can
accommodate a maximum of +30 Vdc,
1.2-A current carrying capacity, and
0.5-A current switching. The switches
(SW1 and SW2) can trigger fraction
collectors and other external devices.
They can also activate according to time,
absorbance threshold, or ratio criteria.
Thermal wander management The detector's insulation, fans, and
baffling are designed to mitigate thermal
instability caused by ambient
temperature changes.
Median Baseline Filter (MBF) A variation of the data mode, the MBF
decreases the effects of gradient
separations on the chromatographic
baseline. It enhances the UV detector's
baseline stability by decreasing its
curvature, making the development of
integration methods easier.
